📝 Summary: A vulnerability was discovered in the Nextcloud Collectives application that allowed non-members accessing a public collective to create new pages through the backend API, bypassing the collective-level permission settings configured to restrict editing to administrators only. The vulnerability was caused by inconsistent permission enforcement between the user interface, collective settings, and backend API.
